I looked carefully and noticed that the clipboard part is not absolutely flat. the left and right edges are a little bit bent toward the keyboard. the keyboard part is absolutely flat. anyone noticed that too? or just a situation of mine?
(how to notice it: method 1, place a ruler on the clipboard part; method 2, look with your one eye closed at an angle nearly parallel to the left or right edge of clipboard part, as shown in the picture)
